Gosh... Have you tried engaging the seller then? I have always worked for the initial purchaser, who is my employer, but if I were a seller and this happened, I would probably RMA it for you at most charging you shipping.
Ruckus actually covers the shipping in our case they send the replacement with a return label. That said, we have had very few devices fail overall... Not a single 6610 at this point in time *knocks on wood*
